Transcript for Amy Brenneman 'Had to Let It Go' When It Came to Being Understood by the Audience

Amy Brenneman stars in HBO's "The leftovers," the premise of this mysterious show % of the world's population has disappeared and no one has any idea why. Amy is here to tell us about this very compelling show and, Amy, I love your character because I mean as an actress this has to be such a challenge. She doesn't speak after joining this cult. How do you convey your feelings? What is it like as an actress? You know, part of it's easy. I don't have to learn lines. When Damon first pitched me this idea, I mean I genuinely like to watch people and listen to people and when my character started doing more things and taking action and some of the actions are not going to be particularly liked by the audience, then I thought, you know, I tapped into that piece of me that wants to be liked and understood by the audience and had to let it go. Mystery is a great word for it. Exactly. Speaking of letting it go, I mean you really go there because you don't even wear any makeup. Yeah. On the show. Yeah. I sort of dove into the pilot and, you know, I'm a bit of a tomboy. No problem. And I saw it last September and I was like, oh, my god. I mean, this has gotten so much buzz and there are already theories and speculations out there about exactly why 2% of the population has been missing. Have you heard some of those theorys and does one stand out to you as the craziest. My dear friend at the premiere said I know what it is. You are departed. I said, what do you mean? Like I'm a person. She's like, no, but you don't speak. So she had this whole like we're in sort of heaven and -- I was like, no, that's totally wrong. Back here in reality you are a supermom of two. I heard that when you're with your children, you do not look at your phone. Well, I try not to. I do -- they're going to watch this and go what. My daughters call me Mrs. Text-a-lot. I know. I try not to mostly -- I have a 13 and 9-year-old and don't want them to do it to me much as a family, culture, we're trying to figure the mores. You direct your children's plays at school. Supermom. Badly. I taught a class where I was so relaxed because there was nothing -- there was no product that needed to be made and then as soon as I directed this thing, production of "Annie" I became a shrew and I was like, listen, February 20th, you better -- all of my ease went away. I was like -- as I was doing it I was like, this -- I'm not good at it. I'm not inspiring or fun. Well, you're fantastic in front of the camera. Amy Brenneman, a pleasure to have here and what an incredible, incredible show. We're all going to be binge watching "The leftovers" airs Sunday nights on HBO. ? Suddenly I see."
